Fix v2.5.5-dev installation issues: handle curl execution and MariaDB upgrade attempts

- Fix install.sh to detect curl/wget execution and clone repo before loading modules
- Add MariaDB detection and upgrade attempt logic in install.py
- Attempt MariaDB 12.1 upgrade first, fallback to existing 10.x if blocked
- Add comprehensive error handling and logging for upgrade attempts
- Update documentation with fix details
